Central Bank
The Central Bank contains various information about the Market, current city valuation, and Offline Earning.
Wallstreet
- Market Cap is the total market value of the current city.
- Building Valuation is the total value of all structures including building permits and upgrades.
- Resource Valuation is total value of all resources in storage, including held cash.
The city market cap is calculated by adding the building valuation and resource valuation and multiplying it by the stock rating:
(buildingValuation + resourceValuation) * stockRatingSwiss money 
for the city is calculated by the following formula:
cubeRoot(((buildingValuation + resourcesValuation) * stockRating) / 1,000,000)To calculate the inverse, or the Market Cap needed to earn a desired amount of Swiss money, use the following formula:
cube(desiredSwiss) * 1,000,000 * ((buildingValuation + resourcesValuation) * stockRating)Because the formula is cubic, while 1B Market Cap is 10 Swiss money it takes 1T Market Cap to gain 100 Swiss money, not 10B or 100B.
For those not familiar:
cube(desiredSwiss) = desiredSwiss * desiredSwiss * desiredSwissStock Rating is a random multiplier ranged between 0.5 and 1.5. The multiplier is updated each market cycle and is the same for all players, except for players in Hong Kong, which resets every hour rather than every two hours. The multiplier can be converted to percentage as outlined below:
| Name | Range | Min % | Max % |
|---|---|---|---|
| Sell | 0.5 - 0.7 | -50% | -30% |
| Underperform | 0.7 - 0.9 | -30% | -10% |
| Hold | 0.9 - 1.1 | -10% | +10% |
| Outperform | 1.1 - 1.3 | +10% | +30% |
| Buy | 1.3 - 1.5 | +30% | +50% |
Combining the formula and table, it is best to Cash In when the highest building and resource valuation can be reached and the stock rating is indicated as Buy.
Note: Stock Rating does not determine resource pricing in Trade Center.
Because the cubic root is outside of the stock rating, if a stock rating were to double (e.g. 0.6 -> 1.2) that does not equate to double the Swiss money earned. Example:
cubeRoot((45,000,000 * 0.6) / 1,000,000) = 3 Swiss money
cubeRoot((45,000,000 * 1.2) / 1,000,000) = 3.8 Swiss money
Offline Earning
The Offline Earning rate is calculated from Market Cap and Overnight Interest Rate. The value displayed in the Central Bank includes the interest rate. After the Offline Earning Time threshold is met due to being offline for at least the specified amount of time no more offline cash will be accrued.
Overnight Interest Rate is calculated from price, production surplus, Auto Sell Capacity and Concurrency, and Stock Rating.
Only cash 
is earned from offline earning. Resources, Research Points, Culture Points, Auto Sell, etc are paused until returned online.
